Im having an issue where when I start the truck cold, it makes this very loud hissing sound like my boost is just blowing out somewhere until I give it more throttle and it stops. If I poke around, it will do it almost non-stop. I know the intercooler pipes aren't leaking- done had them checked for that. There is a loss of power when this leak occurs too. It's really beginning to worry me, but once the engine is warm it goes away and performs just fine. Only does it when dead cold. BTW, it's a 2000 xcab 7.3 6-speed 2wd 252,xxx miles.

Thanks guys, I have only had the truck about 6 months, and this is my first cold weather with a diesel. Already discovered the benefits of having a good pair of batteries. This one was freaking me out. Also, just put my Tymar intake on Wednesday. Love the way it sounds. I don't like how it deletes the IAT sensor though.

Or else make a Sticky thread encouraging people to search something like this common "problem" for at least 2 seconds befor posting. Like the 745 threads started with titles like "Truck dies, then worked ok, then dies with tach not working." Its the same thing over and over again.
